I'm not going to be much help, other than to sympathize. Since about
6 months before I was diagnoised I have had skin issues. Hives that covered my entire body for head to foot that last two weeks, then I got big ugly red bumps on my legs (eurthym nodusum - which are related to crohns), when I ended up in the hospital I had small red pimple size soars all over my body (no one ever diagnoised these, I guess there were too many other pressing issues at that point), then I had psoriasis that was from scalp to feet - it has "healed" after 4 months of uvb treatments but now I have brown spots all over my skin which I am told are now scars. Some of these came before, some during major flares. My best advice is to see a Derm again and hopefully they will have some information for you. Hope that you find some answers soon,
Living with Crohns for 1 year. I have a wonderful husband and two beautiful little girls.
One blessing that came with my Crohns: I thank God for each day that I can get out of bed and take care of my girls and my home.
